Ontario Cannabis Laws Explained: Age, Limits and Where You Can Use It

The legal age, the 30 gram limit, where you can buy and where you can't smoke or vape: Ontario's cannabis rules in plain language, with official sources.

Ontario's cannabis laws come down to four rules: you must be 19 or older, you can carry up to 30 grams of dried cannabis (or the equivalent) in public, you can buy only from the Ontario Cannabis Store or an authorized retail store, and you can't smoke or vape it in enclosed public places, workplaces and a list of other protected spots. Below is each rule in plain language, as of 2026, with a link to the official page behind it.

The legal age in Ontario is 19

The Government of Ontario's cannabis laws page is clear: you must be 19 or older to buy, use, possess and grow recreational cannabis. That matches the minimum age for alcohol and tobacco in the province.

The legal age is set by each province and territory, so it isn't the same everywhere in Canada. Health Canada notes it is 18, 19 or older depending on where you are. If you are visiting from another province, Ontario's age of 19 is the one that applies here.

What that means at a store counter:

• Authorized stores must not let anyone under 19 in, and the AGCO says staff must check the ID of anyone who appears to be under 25.
• At Sugar Beach Cannabis we are 19+ only and ask for government photo ID.
• Ontario runs a Youth Cannabis Diversion Program for youth aged 12 to 18 who come into conflict with the law over certain provincial cannabis offences.

How much you can carry: 30 grams

Adults can have a maximum of 30 grams of dried cannabis, or the equivalent, in public at any time. The same 30 g figure is the most you can buy in a single transaction, whether you buy from the Ontario Cannabis Store online or from an authorized store.

"Equivalent" matters because most products aren't dried flower. The federal Cannabis Act sets the conversions in Schedule 3. A few common ones:

Where you can buy cannabis legally

In Ontario there are only two legal ways to buy recreational cannabis:

1. Online from the Ontario Cannabis Store (OCS.ca), the province's own online retailer.
2. From a privately run store authorized by the AGCO (Alcohol and Gaming Commission of Ontario). These stores buy all of their products from the OCS, and the AGCO allows them to take online orders for in-store or curbside pickup.

Authorized stores display the provincial Cannabis Retail Seal where you can see it from outside the entrance, and you can confirm any store on the AGCO's official map. Ontario warns that buying from any other source can bring a fine of up to $100,000 and/or up to one year in prison. Our guide on how to tell if a dispensary is licensed shows you the checks step by step, and OCS vs a licensed dispensary explains how the two legal options differ.

Where you can and can't use cannabis

Ontario lets adults smoke or vape cannabis in:

• Private residences (not a residence that is also a workplace), subject to your lease or condo rules
• Many outdoor public places, for example sidewalks and parks
• Designated smoking guest rooms in hotels, motels and inns
• Residential vehicles and boats that meet certain criteria

You can't smoke or vape cannabis in places that include:

• Enclosed public places and enclosed workplaces
• Indoor common areas of condos, apartment buildings and university or college residences, such as hallways, elevators and lobbies
• School grounds, children's playgrounds and public areas within 20 metres of them
• Child care centres and home child care premises
• Restaurant and bar patios and public areas within 9 metres of a patio
• Publicly owned sports fields, nearby spectator areas and public areas within 20 metres
• Sheltered outdoor areas with a roof and more than two walls, such as bus shelters
• Within 9 metres of hospital entrances and on the grounds of hospitals and psychiatric facilities

Ontario's where you can't smoke or vape page lists fines of $1,000 for a first offence and $5,000 for any further offence if convicted. Toronto adds its own rules for parks and building entrances. We cover those in where you can smoke cannabis in Toronto.

Vehicles and boats

You can't consume cannabis in any way (smoking, vaping or eating) in a vehicle or boat that is being driven or will be driven. It is also illegal to transport cannabis in a car or boat if it is open and not in its original packaging, or if it is loose and within reach of anyone in the vehicle. Driving while impaired by cannabis is a criminal offence, and young, novice and commercial drivers must have zero cannabis in their system. Full details are in our cannabis and driving guide.

Growing cannabis at home

Adults 19 and older can grow up to four plants per residence, not per person, for personal use. Seeds or plants must come from the Ontario Cannabis Store or an authorized retail store, and your lease or condo rules must not forbid it.

Edibles

Edibles have been legal in Canada since October 17, 2019. Ontario's page notes that each package can contain up to 10 mg of THC, and edibles may not contain nicotine or added alcohol. For first-time buyers, that small per-package amount is a good reason to start low and wait before having more.

Crossing the border

Taking cannabis across the Canadian border, in or out, is illegal in any amount, even if you are travelling to a place where it is legal. That includes products containing CBD. If you are flying, read flying with cannabis from Toronto before you pack.

Responsible use, in short

• Start low and go slow, especially with edibles.
• Never drive or operate a boat after consuming.
• Keep cannabis locked up and away from children and pets.
• Talk to a healthcare provider if you have questions about medical use. Medical cannabis follows separate rules.
